from the Guardian - global scheme, agreed to by 191 nations, applies to passenger and cargo flights that generate more than 1,000 tonnes of greenhouse gases annually
"The world’s first agreement to curb aviation’s greenhouse gas pollution has been struck by 191 nations in a landmark United Nations accord, although environmental groups have warned the deal doesn’t go far enough.
A meeting of 2,000 delegates at the International Civil Aviation Organization(ICAO), a UN agency, in Montreal has settled upon a global emissions-reduction scheme that will apply to passenger and cargo flights that generate more than 10,000 tonnes of annual greenhouse gases.
The deal, aimed at reducing the growing climate impact of plane travel, follows years of disagreement between nations on how to slow emissions from the sector. Instead of facing a cap or charge on emissions, airlines will be involved in an offsetting scheme whereby forest areas and carbon-reducing activities will be funded, costing about 2% of the industry’s annual revenues. Global aviation emissions in 2020 will be used as a benchmark, with around 80% of emissions above 2020 levels offset until 2035.
The new system will be voluntary until 2027, but dozens of countries, including the world’s two largest emitters, the US and China, have promised to join at its outset in 2020. Campaigners hope that this will spike ambition to make aviation carbon neutral."
