Northern Ireland's politicians have been urged to end the procrastination on climate targets as world leaders gather in New York today for the UN Climate Change Summit.
Overseas development charity Trócaire warned that failing to produce a climate deal means a death sentence for millions of the world's poor.
Lorna Gold, head of policy and advocacy at the Irish charity, called on the UK and Irish governments as well as Stormont to get firmly behind efforts to reduce global carbon emissions. Speaking from New York, she said: "Climate change is the greatest injustice of our time. The people who are doing least to cause it are suffering the most, while those with most power to address it have so far utterly failed to do so.
"All over the developing world, people are struggling to survive in the face of drought, storms and floods. They are on the front lines of the battle against climate change but when they look for support, they are met only by feeble excuses.
"After years of delays and procrastination, political leaders simply must deliver. We need a global response to what is a global problem. But this problem must be tackled not only at international and national level but at regional level also. We call on the NI Assembly to introduce a Northern Ireland Climate Change Act with a legally binding regional target to reduce carbon emissions from 1990 levels by at least 40% by 2020 and 80% by 2050."
