In an effort to limit telemarketers who had taken to bombarding users with hordes of unsolicited messages, India introduced new regulations in September 2011, including a cap of 3,000 SMS messages per subscriber per month, or an average of 100 per subscriber per day. Due to representations received from some of the service providers and consumers, TRAI (Telecom Regulatory Authority of India) has raised this limit to 200 SMS messages per SIM per day in case of prepaid services, and up to 6,000 SMS messages per SIM per month in case of postpaid services with effect from 1 November 2011. However, it was ruled unconstitutional by the Delhi high court, but there are some limitations.
Santa Monica is one of the most environmentally activist municipalities in the nation. The city first proposed its Sustainable City Plan in 1992 and in 1994, was one of the first cities in the nation to formally adopt a comprehensive sustainability plan, setting waste reduction and water conservation policies for both public and private sector through its Office of Sustainability and the Environment. Eighty-two percent of the city's public works vehicles now run on alternative fuels, including nearly 100% of the municipal bus system, making it among the largest such fleets in the country. Santa Monica fleet vehicles and buses now source their natural gas from Redeem, a Southern California-based supplier of renewable and sustainable natural gas obtained from non-fracked methane biogas generated from organic landfill waste.
Santa Monica has adopted a Community Energy Independence Initiative, with a goal of achieving complete energy independence by 2020 (vs. California's already ambitious 33% renewables goal). In the last 15 years, greenhouse gas emissions have been cut citywide by nearly 10% relative to 1990 levels, with further reductions being planned by the Office of Sustainability.
An urban runoff facility (SMURFF), the first of its kind in the US, catches and treats 3.5 million US gallons (13,000 m3) of water each week that would otherwise flow into the bay via storm-drains and sells it back to end-users within the city for reuse as gray-water, while bio-swales throughout the city allow rainwater to percolate into and replenish the groundwater supply. The groundwater supply in turn plays an important role in the city's Sustainable Water Master Plan, whereby Santa Monica has set a goal of attaining 100% water independence by 2020. The city has numerous programs designed to promote water conservation among residents, including a rebate of $1.50 per square foot for those who convert water intensive lawns to more local drought-tolerant gardens that require less water.
Santa Monica has also instituted a green building-code whereby merely constructing to code automatically renders a building equivalent to the US Green Building Council's LEED Silver standards. The city's Main Library, for example, is one of many LEED certified or LEED equivalent buildings in the city. It is built over a 200,000 gallon cistern that collects filtered storm water from the roof. The water is used for landscape irrigation.
Since 2009, Santa Monica has been developing the Zero Waste Strategic Operations Plan by which the city will set a goal of diverting at least 95% of all waste away from landfills, and toward recycling and composting, by 2030. The plan includes a food waste composting program, which diverts 3 million pounds of restaurant food waste away from landfills annually. Currently, 77% of all solid waste produced citywide is diverted from landfills.
The city is also in the process of implementing a 5-year and 20 year Bike Action Plan with a goal of attaining 14 to 35% bicycle transportation mode share by 2030 through the installation of enhanced bicycle infrastructure throughout the city. Other environmentally focused initiatives include curbside recycling, curbside composting bins (in addition to trash, yard-waste, and recycle bins), farmers' markets, community gardens, garden-share, an urban forest initiative, a hazardous materials home-collection service, green business certification, a municipal bus system, and the Metro light rail Expo Line (replacing the former Pacific Electric Santa Monica Air Line last operated in 1953).
