United Nations, September 24 (Xinhua-RHC) -- Costa Rica on Tuesday called for "cheaper, innovative and accessible" technologies to help the Latin American country to development renewable technologies in its efforts to tackle climate change.

Costa Rican President Luis Guillerno Solis Rivera made the call while addressing the UN Climate Summit, which opened at the United Nations headquarters in New York earlier Tuesday.

"My government is committed to the massive development of renewable technologies for domestic use," he said. "We believe Cost Rican families must acquire appropriate, affordable and sustainable energy consumption patterns using the best technologies available."

These technologies should be cheaper, innovative and accessible to everyone, he said. "Similar efforts are being undertaken in public institutions, for which we are designing new strategies of consumption that will result in significant savings of resources and will redefine the public energy-saving strategy."

"These are complex and difficult goals to achieve, for this reason, it is fundamental that the international community provides support to middle-income countries like Costa Rica," he said. "Our efforts must be based in a real international solidarity in order to benefit from a real and effective global alliance."

According to the president, this alliance must not penalize or discourage our progress towards a low emissions development path and the achievement of poverty eradication.

The Costa Rican president was among more than 120 heads of state or government who attend the one-day summit at UN headquarters in New York, which aims to raise ambition, mobilize resources, and generate action toward a universal climate deal in 2015.
