The US is believed to have made small concessions over forests and nuclear power but is thought to be reluctant to accept a compromise forcing it to take action to cut domestic emissions. Cut back on travel. One return flight to Rio de Janeiro burns as much carbon per passenger as 230 train journeys between Oxford and London.
Trains are more energy efficient per person than cars, but less so than bicycles.
The surest method of not burning carbon, however, is to walk. Reduce dependence on oil and fossil fuels. Consider low energy light bulbs and solar power. Switch your electricity supply to renewables. All energy companies now have schemes.
