Huge emissions savings in lighting and appliances at world’s fingertips
The Climate Action Tracker, as part of its decarbonisation series, today released its analysis on the emissions reduction potential for lighting and appliances in buildings. If the highest existing minimum energy performance and labelling standards were applied globally, they could save around 4,500 TWh in 2030, the equivalent of closing 1,140 average coal-fired power plants (600 MW).
Coupled with low carbon electricity, applying these standards globally could reduce annual emissions by 5.2 GtCO2 in 2030 (-60%) compared with business-as-usual—more than the current annual emissions of the entire European Union.
“More efficient appliances and lights use less electricity and therefore help the power sector to phase out emissions from fossil fuels, a crucial enabling factor towards achieving the 1.5°C warming limit,” said Dr Ursula Fuentes of Climate Analytics.
The analysis looks at case studies such as in India where a programme to address the financial barrier of higher LED costs has sold more than 230 million LED bulbs to Indian households since 2014 (the demand has increased by 50 times). This resulted in electricity savings of more than 30 TWh annually and an avoided peak demand of 6,000 MW.
“What we found amounts to an obvious business case, with tremendous opportunities for both manufacturers and customers,” said Yvonne Deng of Ecofys, a Navigant company.
In France, lighting installations of non-residential buildings must be switched off at night, to reduce both energy waste and light pollution. The resulting energy savings are comparable to the annual electricity consumption of 750,000 households, will lower CO2 emissions by 250 kt and save French businesses EUR 200 million in energy costs.
“We found examples around the world where people are reaping the benefits by switching off lights in cities at night, switching to LEDs, smart lighting and smart metering, apps provided by energy companies to encourage customers to save energy or to use appliances at off-peak hours” said Prof Niklas Höhne of NewClimate Institute.
Over one billion people have no access to electricity, and one in three still use kerosene for lighting, which has major health impacts. For these people, off-grid solar lighting or microgrid renewable energy solutions with efficient lighting continue to offer tremendous opportunities in avoiding greenhouse gas emissions while stimulating social and economic development.
“Lighting and appliance efficiency improvements, together with renewable energy, are key to simultaneously meeting the sustainable development goal of providing access to affordable and clean energy for all and the Paris Agreement 1.5°C limit,” said Jasmin Cantzler of Climate Analytics.

Projected warming almost unchanged for two years as governments push false solutions over climate action
Despite their promises, governments have not taken enough action to drive down warming projections, with some instead turning to false solutions such as carbon capture and storage to continue the world's reliance on fossil fuels, according to the Climate Action Tracker's annual warming update.
All greenhouse gas emissions could peak in 2023
A new report finds maintaining current solar, wind and electric vehicle growth rates could lead to peak emissions in 2023.
Oil and gas majors could have paid for their share of climate loss and damage and still earned 10 trillion USD: new report
Global climate damages from emissions associated with the top 25 oil and gas ‘carbon majors’ between 1985 and 2018 are estimated at 20 trillion USD compared to the 30 trillion USD they earned over the same period, according to a new report released today by international think tank Climate Analytics.
A 1.5˚C pathway for the Philippines power sector entirely feasible: analysis
With the right international funding and policies in place, the Philippines could transition its’ power sector to near-100% renewable energy without compromising on the costs of electricity, reducing its reliance on expensive imports of both coal and gas, and creating up to a million jobs by 2050.
State of Climate Action report finds progress lags on every measure except EV sales
Global efforts to limit warming to 1.5°C are failing across the board, with recent progress made on every indicator — except electric passenger car sales — lagging significantly behind the pace and scale that is necessary to address the climate crisis.
Governments plan to produce double the fossil fuels in 2030 than the 1.5°C warming limit allows
The Production Gap Report finds governments plan to produce around 110% more fossil fuels in 2030 than would be consistent with limiting warming to 1.5°C, and 69% more than would be consistent with 2°C.
Beetaloo fracking and Middle Arm emissions wildly underestimated: analysis
An independent analysis of the projected emissions from the Northern Territory's proposed Beetaloo Basin gas fracking project — and the associated Middle Arm LNG precinct in Darwin Harbour — has found they've been gravely underestimated, as have the availability of offsets to deal with them.
