Key steps in the next decade toward the 1.5°C warming limit
The latest Climate Action Tracker report spells out important, short-term steps over the next ten years that key sectors need to take to help the world achieve the Paris Agreement’s 1.5°C limit. Here are some of the steps the big sectors can take – and some examples of what is already happening.
All key sectors – energy generation, road transport, buildings, industry, forestry and land use, and commercial agriculture – have to begin major efforts to cut emissions by, latest, 2020. By 2025 they should have accelerated these efforts in order to reach a globally aggregated zero carbon dioxide emissions by mid-century.
These ten steps are crucial to achieving a complete decarbonisation of our economies over the next 34 years. It may seem like a daunting task but the transition is already underway.
Below are some of the steps the big sectors can take – and some examples of what is already happening.
Renewables are conquering the power sector across the globe: 2015 was a record year for renewable energy with an estimated 147 gigawatts added – the largest ever increase in capacity installed. Wind and solar production has increased by 25-30% year on year, and if this continues until 2025, we will be well on the way toward achieving the zero emissions goal in 2050.
At the same time, the era of king coal seems over, with more and more producers and investors moving away from coal and towards renewables. We find that no single new coal-fired power plant can be built – from today, and those already operating need to reduce their hours and be shut down early.
The transport sector has begun the shift towards electrification. Just a few days ago, Jaguar announced to launch its first electric car and Renault plans a low cost $8,000 electric car for 2018, illustrating the increasing dynamic and expectations of the market towards electric vehicles. China is the leading nation in EV’s, with 330,000 new vehicles sold in 2015 alone. We find that no new fossil fuel powered car can be sold after 2035. Your petrol-fuelled car will become a thing of the past.
One of the best-funded start-ups of the decade has developed a plant burger that smells and tastes and sizzles like meat, showcasing the innovative force within the industry to reduce emissions from livestock rearing that account for 55% of the emissions in the agriculture sector. China recently revised its dietary guidelines, advising individuals to limit their meat consumption to between 40g and 75g a day, half of current consumption levels. This is the type of action we need to see, along with best-practice in farming methods.
If food wastage were a country, it would be the third largest emitting country in the world and it is estimated that up to 14% of emissions from the agriculture sector could be avoided by managing better food use. Many innovative business ideas try to overcome this challenge through the use of big data and governments such as France are leading the way in reducing food waste.
Two other sectors where rapid action would bring significant emissions reductions are buildings and industry.
We find that starting now, all new buildings need to be zero emissions and current building stock must be renovated and retrofitted at an increased rate. but we are not deploying it. If new buildings going up now are not up to this standard, they will need to be retrofitted later on – already one of the most challenging tasks for governments to tackle.
In the Netherlands, social housing corporations have committed to achieve an average energy level B (on a scale from A to G) in their existing housing stock by 2020. Mexico has improved the energy efficiency of millions of buildings by providing a “green mortgage”, targeting both refurbishments of old buildings, and construction of new buildings. If countries with a similar climate were to adopt the Mexican green mortgage programme, it could reduce annual emissions by 129 MtCO2e by 2030.
Emissions from industry need to drop by well over 50% by 2050. To get there, we find that all new industrial installations need to be built according to the best available low carbon technology standard from 2020 onwards. The steelmaking sector, for example, would need to stop building conventional blast furnaces.
China’s Top-10,000 programme improved energy efficiency across industry on average by 3 to 4%. Scaling up the solution could reduce emissions by a significant amount while cutting energy bills for industry and reducing local air pollution.
All this goes to show that the transition towards clean technologies and zero emissions is gaining traction across the board, thereby changing the economic equation and increasingly showcasing that this transition makes economic sense and improves the bottom line across industries. It increases universal energy access, creates approximately double the number of jobs by 2050 than current policies, improves energy independence and reduces risks of fossil fuel impacts.
What is needed in the next few years is consistent and predictable policy support to accelerate these positive developments already underway. Policy makers have the responsibility to set the course into a decarbonised world, to create the environment to enable an acceleration of actions across all these sectors.
COP28: social and economic metrics could serve as stepping stone for Global Goal on Adaptation
As work on shaping the Global Goal on Adaptation culminates this week at COP28, we explore if social and economic metrics could be used as proxies for a country’s ability to adapt.
Safeguards and exit points for the World Bank as host of the Loss and Damage Fund
An agreement was reached to establish the World Bank as the interim host of the Loss and Damage Fund. Developing countries signed up to this on certain conditions. We unpack the safeguards put in place and look at the three points at which the Fund could exit the World Bank.
Beetaloo gas field is a climate bomb. How did CSIRO modelling make it look otherwise?
The fossil gas industry is gearing up for a truly enormous new fracking project in the Northern Territory’s Beetaloo Basin that could undo all Australia's efforts to cut emissions.
From droughts to floods: how Eastern African countries are responding to the rising El Niño and Indian Ocean Dipole
The Horn of Africa looks set to go from one disaster to another as floods intensified by a rising El Niño and a positive Indian Ocean Dipole are predicted to follow a prolonged drought. We take a look at climate policies in the region and what countries are doing to prepare for compound extreme events.
The just transition looks different for small islands – their voices must be heard
The concept of a just transition is gaining momentum, yet it’s too often viewed through a developed country lens in international climate talks and discussions often ignore the links to climate justice. The unique concerns of small islands must be heard to ensure the just transition works for all.
Overshoot Commission’s veneer of neutrality is solar radiation modification PR by stealth
Calls for a moratorium on solar radiation modification (SRM) today by the Overshoot Commission seem sensible – such sun-blocking technologies are highly risky. Yet in the same breath, the Commission appears to encourage moratorium-busting SRM testing, begging the question – is their new report a trojan horse?
Loss and damage: two options in play for fund’s makeup
There are currently two options on the table for the loss and damage fund’s structure – ‘programmatic’ and ‘responsive’. We reflect on the pros and cons of each.
El Niño is contributing to the hottest temperatures ever recorded – what does this mean for the Paris Agreement’s 1.5°C limit?
Extreme weather is raging across the northern hemisphere. Our experts explain the implications of the emerging El Niño for our changing climate.
